We Are All Made of Stars
The scientists, from Europe and the USA, say that their research, published in the journal Earth and Planetary Science Letters, provides evidence that life’s raw materials came from sources beyond the Earth.
The materials they have found include the molecules uracil and xanthine, which are precursors to the molecules that make up DNA and RNA, and are known as nucleobases.
The team discovered the molecules in rock fragments of the Murchison meteorite, which crashed in Australia in 1969.

Lead author Dr Zita Martins, of the Department of Earth Science and Engineering at Imperial College London, says that the research may provide another piece of evidence explaining the evolution of early life. She says:
“We believe early life may have adopted nucleobases from meteoritic fragments for use in genetic coding which enabled them to pass on their successful features to subsequent generations.”
Between 3.8 to 4.5 billion years ago large numbers of rocks similar to the Murchison meteorite rained down on Earth at the time when primitive life was forming. The heavy bombardment would have dropped large amounts of meteorite material to the surface on planets like Earth and Mars.
Co-author Professor Mark Sephton, also of Imperial’s Department of Earth Science and Engineering, believes this research is an important step in understanding how early life might have evolved. He added:
“Because meteorites represent left over materials from the formation of the solar system, the key components for life — including nucleobases — could be widespread in the cosmos. As more and more of life’s raw materials are discovered in objects from space, the possibility of life springing forth wherever the right chemistry is present becomes more likely.”
Science rules.

I feel you jim, Primus is the worst company. it is very bad that they carry Canada name behind their name “Primus”, I signed up for the VOIP and it was the worst choice I have ever made. then I decided to more to regular phone line and they asked for $50 connection fee. it took them 7 days to transfer the phone. my family lived with no phone or internet for complete 7 days. then they offered me a very good offer on the internet. so they promised me to get the internet and they never did. I lived without internet for about a week again. then I said fuck it and called Rogers and got a phone service and internet from them it took them 1 day to set everything. I rather pay more but not to live in this shit.
Great photos
I agree with Mark. I do not find this movie depressing per say … but simply brilliantly written. I have the whole show memorized too … and I can watch it over and over again. And God bless Leonard Frey … what an actor !
My dear sir:
It has come to my attention by means of my attentiveness that you haven’t said much lately. Ahem ahem. If you let it go to a month, you’ll start to grow the impression that you have to explain, blah blah, and that the post has to be awesome to compensate etc. I therefore must urge you with great urgings to get something up here before November 24th. You can talk about how mustache-growing affects kissing on the part of the kisser (I know about the kissee already). Or the weather. What you had for lunch. I’m just saying, immediate action must be taken to avoid certain disaster. Or something. Please. Pretty please.
K primus is shit..
heres the story..

Soooo…Where the F are you? You can’t tell me that life in Van is so fabulously awesome that there is nothing to complain about! Is that city so perfect, are the roads so pothole free, are the politicians so straight that there is nothing to talk about? Or.. are you sick … that tiresome sinus issue you have? Us loving followers (yes from Toronto) need to know?
@anne & SkippyBoy: Thanks for the votes advocating more posts. They’re coming. Truth is, I’ve been working more hours than usual and diving, headfirst and enthusiastically, into establishing a social network here in Vancouver. Life is good here, very good.
Sometimes, I feel sad that there’s so much negativity on the Internet. Whether or not you like, dislike, or have no particular opinion on someone, I just don’t think it’s very nice to be so mean.
I guess I just wish people were sweeter.
This is terrible. I was on another site http://www.timhortonsfranchise.com and see they don’t treat thier franchisees any better. This is disgusting what a giant corporation can do. Spread the word.
I think it’s JUST adorable! There’s something rather touching about the small pox and polio notes to me. You’re right Brett, it’s become something better than useful, it’s become art.
let me add a voice to those advocating more posts. i miss you too and will keep checking.
hope you guys have great holidays in your new home.
I’m adding my voice to the chorus of people who want, nay, NEED posts from you, Brett. Please post soon! We miss the Canadian snark!
Missing ya, man, but glad it’s for good reasons, not bad. Hope to see you posting again soon!
